and git commit -m "add additional content to README". If we git push right away, we still won't get the changes because we have not tracked and committed the changes.Let's fix this by pushing our code up to GitHub. Notice that the new text in your README is not there. Now look at the remote repo on GitHub.Open the file, and add whatever text you'd like. Let's add some new content to our README.md file.This sets the remote, so you can push and pull code. git remote add origin your-remote-repository-URL.Add and commit the new file we created in the my_new_directory directory. (We'll use this in the next section.)Ĭonnecting your remote repo to a local repo Click the "Copy to clipboard" symbol on the right-hand side of the screen ( ) to copy the clone URL. After you create the repo, you should see a "Quick setup" page.Click the green Create repository button. You can name it whatever you'd like be creative! The default options are fine as-is - don't initialize the new repository with a README or add a. Enter a name for your repository in the Repository name field.While logged into GitHub, click the in the menubar and select New repository.Add some text to the new file: echo "This is my readme file" > README.md.Create a new file named README.md: touch README.md.Change into the newly-created directory: cd my_new_directory.Create a new directory named my_new_directory: mkdir my_new_directory.If your development directory is named something other than ~/code, that's fine - cd into whatever yours is called.Change into your code directory: cd ~/code.You can run this series of commands in the terminal: Let's go through an example to clarify remote repositories on GitHub. Use git push to connect your local repository of files to your remote repository.Describe GitHub and its relationship with Git.The best resource I’ve found for understanding Git and GitHub comes from this 2016 talk ( slides here) by Alice Bartlett of the Financial Times (hat tip to Garrick Aden-Buie of RStudio for telling me about it). Git and GitHub have built-in tools that enable simultaneous asynchronous work, a major benefit for those working in teams. The problem they run into is that only one person can work on an RStudio project shared in this way. Many of the teams I train that are learning R decide to switch to Git/GitHub after collaborating using Dropbox, Google Drive, OneDrive, or the like. Using Git and GitHub makes it possible to work on the same project at the same time as collaborators.Instead of making copies of files over fear of losing work, version control allows you to see what you did in the past, all while keeping single versions of documents. Ever had documents called report-final.pdf, report-final-v2.pdf, and report-final-v3.pdf? Yes, yes, you have. Using Git and GitHub allows you to use version control. Because GitHub has a copy of all of the code you have locally, if anything were to happen to your computer, you’d still have access to your code.
